Penjelasan dengan langkah-langkah:

Volume kerucut = 1/3 x π x r² x t

s = garis pelukis

r = hati2

t = tinggi

1. tinggi = √s² - r²

t = √10² - 8²

t = √100-64

t = √36

t = 6 cm

V = 1/3 x π x r² x t

V= 1/3 x 3,14 x 8² x 6

V = 3,14 x 64 x 2

V = 401,92 cm³

2. V = 1/3 x π x r² x t

V = 1/3 x 22/7 x 7 x 7 x 24

V = 22 x 7 x 8

V = 1.232 cm³

3. d = 32 cm

r = 16 cm

V = 1/3 x π x r² x t

V = 1/3 x 3,14 x 16² x 30

V = 3,14 x 256 x 10

V = 8.038,4 cm³

4. r = √s² - t²

r = √17² - 15²

r = √289 - 225

r = √64

r = 8 cm

V = 1/3 x π x r² x t

V = 1/3 x 3,14 x 8² x 15

V = 3,14 x 64 x 5

V = 1.004,8 cm³

5. r = 20 cm

V = 1/3 x π x r² x t

V = 1/3 x 3,14 x 20² x 21

V = 3,14 x 400 x 7

V = 8.792 cm³

6. t = √s²-r²

t = √5² - 3²

t = √25 - 9

t = √ 16

t = 4

V = 1/3 x π x r² x t

V = 1/3 x 3,14 x 3² x 4

V = 3,14 x 3 x 4

V = 37,68 cm³
